Question 15: NCERT Solutions for 12th Class Physics: Chapter 2-Electrostatic Potential and Capacitance
A spherical conducting shell of inner radius r, and outer radius r2 has a charge Q.
- A charge q is placed at the centre of the shell. What is the surface charge density on the inner and outer surfaces of the shell?
- Is the electric field inside a cavity (with no charge) zero, even if the shell is not spherical, but has any irregular shape? Explain.
